Not if you, as a naive user, take a freshly installed system and an
unmodified environment. You'll need to make a bunch of changes
before everything will run smoothly:
* Make /usr/ports/distfiles writable by user or set $DISTDIR to
a writable directory
* Make /var/db/ports writable by user or set $PORT_DBDIR to a
* Make each port directory writable -- so the the 'work' directories
can be created -- or set $WRKDIRPREFIX to a writable location.
And in fact, if you go on to do the same deal with $PKG_DBDIR and $PREFIX
plus set $INSTALL_AS_USER then you can install most ports entirely as a
mortal user -- the exceptions being ports that want to run mtree(8) or that
need to install programs with specific UID or GIDs.
Not setting $INSTALL_AS_USER means you'll be prompted to supply the root
password where needed at install time.
